CVE-2021-1245
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCisco Finesse and Cisco Unified CVP OpenSocial Gadget Editor Cross-Site Scripting Vulnerability A vulnerability in the web-based management interface of Cisco Finesse and Cisco Unified CVP could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA cross-site scripting (XSS) vulnerability exists in the web-based management interface of Cisco Finesse and Cisco Unified CVP due to improper validation of user-supplied input. An unauthenticated remote attacker can exploit this by tricking users into clicking crafted malicious links, allowing execution of arbitrary script code in the context of the interface or access to sensitive browser-based information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Cisco Finesse versionAccess the Finesse admin console or use the CLI command 'show version' on the Finesse server to retrieve the installed software versionAffected if The displayed version is 12.0(1) or 12.5(1), or any version lower than 12.0(1)
-
Confirm web-based management interface is enabledVerify that the Finesse web interface (typically on port 8443 or 443) is accessible and actively running. Check via browser access or network port scanningAffected if The web management interface is exposed and the version falls within the affected ranges
-
Verify Finesse is not on a supported patched versionConfirm the exact version number against Cisco's official version listing. Versions 12.0(1) and 12.5(1) are explicitly listed as affectedAffected if Running any version explicitly listed in the affected products: 12.0(1) or 12.5(1)
A system is affected if Cisco Finesse is running with web-based management enabled and the installed version matches 12.0(1), 12.5(1), or any version prior to 12.0(1).

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data12.0
Apply the Cisco software updates released to address this vulnerability. Since no workarounds are available, patching is the only remediation path. Organizations should also consider user awareness training to reduce click-through risk on malicious links.
